I believe you need to go back to the drawing board, and under take some in depth research. Not only into the brewery industry, but also the fundamentals of logo and branding design. (David Airey is a good start).
A logo with this amount of detail will not work when reduced in size, so think much more simple.
Also research into typography, as the current faces don't shout Retro or pop to me. So have a look historically into this.
I hope I have given you some good things to think about on this project. Good luck!
